We know what it’s like to trust a polyclonal that worked last batch but not this one — and to question your own results because of it.
Every antibody in our catalog is one we make ourselves, Western blot validated in-house. Where we have the recombinant protein for a target, you can use it as a positive control from the same source. The Superpooled (SPA) method pools domain-specific polyclonals with predefined epitopes — whole-protein signal with the reproducibility of defined epitopes.
In-house validation, Sudbury — every antibody is tested by the same team that made it.
Built in Sudbury, Ontario. Focused on one problem.
Triple Point Biologics has been making antibodies for proteinases and their inhibitors since 1994. We built the catalog around the proteinase families that matter most for disease research — MMPs, ADAMs, cathepsins, granzymes, kallikreins, BACE, and their inhibitors. Today the catalog spans 981 rabbit polyclonal antibodies and 308 recombinant proteins across those families, all made in-house.
Each Superpooled (SPA) kit pools domain-specific polyclonal antibodies with predefined epitopes, so what’s on the datasheet is what’s in the vial. Same lab, same hands, same QC — for over three decades.
